What does this PR do?

This adds a gzip middleware to fast api for non-streaming responses. This will reduce the number of bytes that needs transmitted over the wire for clients that support it.

FastAPI's provided middleware for this does not play nice with streaming so that is excluded. It unfortunately waits until the connection is closed and sends all data at once.
